Create a RedHat 9.2 Worker Cluster on a CentOS Management Platform

This article explains how to create a RedHat 9.2 worker cluster on an existing CentOS management platform.

Note

This article only applies to the offline mode, using the DCE 5.0 platform to create a worker cluster. The architecture of the management platform and the cluster to be created are both AMD. When creating a cluster, heterogeneous deployment (mixing AMD and ARM) is not supported. After the cluster is created, you can use the method of connecting heterogeneous nodes to achieve mixed deployment and management of the cluster.

Prerequisites

A DCE 5.0 full-mode has been deployed, and the spark node is still alive. For deployment, see the document Offline Install DCE 5.0 Enterprise.

Download and Import RedHat Offline Packages

Make sure you are logged into the spark node! And the clusterConfig.yaml file used when deploying DCE 5.0 is still available.

Download the Relevant RedHat Offline Packages

Download the required RedHat OS package and ISO offline packages:

Resource Name Description Download Link
os-pkgs-redhat9-v0.9.3.tar.gz RedHat9.2 OS-package package Download
ISO Offline Package ISO package import script Go to RedHat Official Download Site
import-iso ISO import script Download

Import the OS Package to the MinIO of the Spark Node

Extract the RedHat OS package

Execute the following command to extract the downloaded OS package. Here we download the RedHat OS package.

tar -xvf os-pkgs-redhat9-v0.9.3.tar.gz

The contents of the extracted OS package are as follows:

    os-pkgs
    ├── import_ospkgs.sh       # This script is used to import OS packages into the MinIO file service
    ├── os-pkgs-amd64.tar.gz   # OS packages for the amd64 architecture
    ├── os-pkgs-arm64.tar.gz   # OS packages for the arm64 architecture
    └── os-pkgs.sha256sum.txt  # sha256sum verification file of the OS packages

Import the OS Package to the MinIO of the Spark Node

Execute the following command to import the OS packages to the MinIO file service:

MINIO_USER=rootuser MINIO_PASS=rootpass123 ./import_ospkgs.sh  http://127.0.0.1:9000 os-pkgs-redhat9-v0.9.3.tar.gz

Note

The above command is only applicable to the MinIO service built into the spark node. If an external MinIO is used, replace http://127.0.0.1:9000 with the access address of the external MinIO. "rootuser" and "rootpass123" are the default account and password of the MinIO service built into the spark node. "os-pkgs-redhat9-v0.9.3.tar.gz" is the name of the downloaded OS package offline package.

Import the ISO Offline Package to the MinIO of the Spark Node

Execute the following command to import the ISO package to the MinIO file service:

MINIO_USER=rootuser MINIO_PASS=rootpass123 ./import_iso.sh http://127.0.0.1:9000 rhel-9.2-x86_64-dvd.iso

Note

The above command is only applicable to the MinIO service built into the spark node. If an external MinIO is used, replace http://127.0.0.1:9000 with the access address of the external MinIO. "rootuser" and "rootpass123" are the default account and password of the MinIO service built into the spark node. "rhel-9.2-x86_64-dvd.iso" is the name of the downloaded ISO offline package.

Create the Cluster in the UI

Refer to the document Creating a Worker Cluster to create a RedHat 9.2 cluster.
